SPINNING OR WINDING MACHINE.

Specification of Letters Patent.

Patented Sept. 16, 1919.

Application filed December 13, 1918. Serial No. 266,587.

The invention to be hereinafter described relates to spinning or winding machines for placing windings of yarn on carriers and has more particular reference to the mechanism for controlling the manner in which the yarn shall be wound upon the carriers.

In. the prior patents granted to George S. Harris, No. 1,167,167, dated January 1, 1916, and to Charles E. Lovejoy No. 1,167,169, dated January 4, 1916, builder motions were described for laying upon yarn carriers or bobbins a yarn mass in which the preliminary windings were laid upon the carriers or bobbins with relatively short traverse and yet with a quick get away, certain features being disclosed for giving to the base portion of the bobbin its proper formation to permit the yarn to be readily delivered therefrom when the yarn carrier or bobbin was used in the shuttle of a feeler loom. In these prior patents the flexible connection or chain between the builder motion and yarn guiding means had secured to it a projection which, by contact with the cylindrical surface of the let-off drum or pulley carried by the builder arm would deflect the flexible connection and, as the let-off pulley or drum was rotated, to gradually progress the traverse upward upon the bobbin or yarn carriers, the projection would permit the connection to straighten out. The characteristic of the deflecting means in the Harris and Lovejoy patents had proved to be of great practical importance, but in adapting this characteristic deflecting means for use in certain kinds of spinning and winding machines, such as a quiller, difliculties have been encountered on account of the small space available between the builder motion and the spindle driving means. An important feature of the present invention, therefore, consists of a flexible connection wherein adjacent portions thereof are so constructed and arranged that the flexible connection may flex in one direction as it passes around one of the cooperating pulleys or drums, but will be prevented from fiexure in the opposite direction as it passes about the other cooperating pulley or drum. In carrying this feature of the invention into effect the flexible connection is preferably formed as a chain, two of the joining links being provided with shim extensions and abutting shoulders, whereby the chain may properly conform to one of the pulleys or drums with which it cooperates and be prevented from conforming with the other pulley or drum with which it cooperates when in contact therewith.

Another feature of importance in the adaptation of the present invention to practice, is the provision of a projection or shoulder on the let-off pulley or drum carried by the builder arm which, in conjunction with the flexible connection between the builder motion and the yarn guiding means, effects the desired deflection and straightening of the flexible connection. 7

The above features of the invention and others will be hereinafter described in connection with the accompanying drawings which disclose a good practical form of the invention.

In the drawings:

Figure 1 represents in front elevation part of a usual quiller frame for winding yarn upon carriers, some of the parts being omitted and others broken away for clearness of illustration;

Fig. 2 is a section on the line 22 of Fig. 1, showing the action of the builder motion during the period of laying the in itial winds upon the filling carriers;

Fig. 3 is an enlarged detail showing the flexible connection and the drums or pulleys with which it cooperates, some of the parts being broken away;

Fig. 4: is a view of the flexible connection and cooperating drums or pulleys with the partsin a different position.

The supporting frame for the quiller may be of any usual or desired character and as herein shown comprises the end frames 1 which are suitably connected by longitudinal members 2 in which are supported for up and down movement the rods 3to which are secured the usual. diagonal frame members 4 between which the guiding wires. of the quiller extend in usual mannor for directing the yarn to the carriers or quills. Any numberof the rods 3 may be employed suitable to the size and structural conditions of the frame as will be readily understood, the construction being such that by the up and down movement ofthe rod 3 and the connected guide frame 4, the yarn to be Wound upon the carriers is properly directed thereto as the carriers are rotated.

One or more of the lifting rods 3 projects downward through its bearing 2 and its lower end is provided with a shoe 5 which rests upon the end of a weighted lever 6 pivoted at 7 to a suitable bracket 8. A weight 9 on the lever 6 normally tends to lift the rods 3 as usual in this class of devices. The lever 6 has the upwardly projecting arm 10 carrying the segment 11 to which is secured one end of the flexible connection 12 extending between the segment 11 and a slabbed off pulley 13 mounted to rotate on an axis 14 supported in suitable bearings 15 carried by the bracket 16, the construction being such that rotation of the slabbed off pulley 13 will control the up and down movement of the lifting rods 3 in this general class of machines.

Mounted for rotative movement upon the machine frame are the spindles 17, Fig. 1,

of which there may be any suitable number and such spindles are provided with whirls or driving pulleys 18 which are driven by a belt 19 from suitable driving means, such as the tin cylinder or drum 20.

Pivotally mounted on the machine frame at 21, Fig. 2, is the builder arm 22 carrying a roll 23 which rests upon the periphery of the builder cam 24 mounted on the builder cam shaft 25 and driven from a suitable source of power which, in the present instance of the invention, is shown as apinion or toothed wheel 26, Fig. 1, the construction being such that as the cam 24 rotates, as usual in this class of machines, the roll 23 is caused to follow the periphery of the cam to thereby effect a traverse of the yarn guiding means, as will more fully appear.

Mounted on the builder arm is the let-off drum or pulley 27, Fig. 2, provided with a worm wheel 28 which meshes with a worm 29 on a usual worm shaft 30 carried by the builder arm. The worm shaft 30 carries the ratchet wheel 31 which, by means of the pawl 32'and actuating rod 33, connected to the swinging arm 34, causes the worm to be progressively rotated as the builder arm rises and falls. The construction thus far described is or may be of usual character, such, for instance, as disclosed in the Lovejoy patent previously mentioned, or of any other desired style.

Rising from the-supporting brackets 16 heretofore mentioned, are the bearing memand a bevel gear 38. Operatively engaged with the bevel gear 38 is the bevel gear 3!) secured to the shaft 14 on which is supported the slabbed off pulley 13 heretofore decribed, the construction being such that retation of the slabbed ofl pulley 13 is controlled through the pulley or drum 37 by the described motion transmitting connections.

Extending between the pulleys or drums 27 and 37 is a flexible connection having adjacent elements thereof constructed and arranged to permit the flexible connection to conform to the surface of the drum or pulley 37 as it winds about such drum or pulley, but to prevent flexure of the flexible connection when the latter is wound about the letoff drum or pulley 27 carried by the builder arm. The let-off drum or pulley 27 is like wise preferably provided with a shoulder to cooperate with the elements of the flexible connection to properly deflect the same. as will more fully appear. The let-oil drum or pulley 27, Fig. 4, has secured thereto a shouldered element 41 provided with an incline portion 42, such connection of the shouldered element 41 and thelet-olf drum or pulley 27 being effected in the present instance of the invention by mean of a screw 43. The shouldered element 41 is extended circumferentially of the let-off pulley or drum 27 and is provided with a lug llthrough which is threaded the adjusting pin 45 having secured thereto one end of the flexible connection or chain 46, the other end of the flexible connection or chain 46 being secured to the pulley or drum 37 as by means of a screw pin 47, Figs. 3 and 4, the construc tion being such that by adjustment of the threaded pin 45 the length of the flexible connection or chain may be adjusted.

The flexible connection or chain -16 has the shim'extension links 48 and 49 which are pivotally connected by a link 50. The shims of these links have shouldered portions .71 which, when the chain is attempted to be flexed about the let-off drum or pulley :27. come into abutting relation and preventflexure of the chain or connection at this point. The shouldered member 41 is preterably situated on the let-oil drum or pulley 27 in position to engage the shim extension links 48 and 49 when the parts are in position for commencing the winding of yarn upon the carriers as best represented by Fi 2. At this time it will be noted that the shim extension links 48 and 49 are not flexed but become substantially rigid and by reason of the shouldered member 41 on the let-olt drum or cylinder 27 cause the flexible connectioirbetween the pulleys or drums to be these links will gradually assume a straightlit) line formation between the tangential position occupied by the flexible connection betially the same purpose as is secured by the difl'erent organization in the prior Harris and Lovejoy patents.

Another feature of the invention is in the association with the character of flexible connection described of the shouldered member 41 and the disposition of the plane of rotation of the let-off drum and pulley 37 in the same or parallel planes whereby the chain. or flexible connection 46 may be uniform throughout with the extension of the shim extension links for causing the described deflecting movements.
